HGS Diamond Taq®

Diamond Taq® polymerases

HGS Diamond Taq® polymerase* is a highly thermostable enzyme produced and purified from recombinant Escherichia coli bacterium containing the Thermus aquaticus DNA Polymerase gene. The expressed enzyme catalyzes 5’→3’ synthesis of DNA with no detectable 3’→5’ proof reading exonuclease activity. This enzyme has the “extendase” activity allowing TA cloning.

HGS Diamond Taq® polymerase HGS Diamond Taq® is a chemically modified HotStart DNA polymerase, which initially lacks all activity below 74 °C. It requires a thermal activation of 10 minutes at 95 °C to reach maximal activity. This avoids non-specific priming at low temperature during the PCR set-up. HGS Diamond Taq® is more heat-stable than commonly used Taq DNA polymerase

HGS Diamond Taq® polymerase is particularly recommended for PCR applications that require ultra low levels of bacterial & fungal DNA in Diagnostic and demanding Research fields but also for amplification of templates prone to produce unspecific amplicons.
